Abstract
Description
Technical Field
[0001] This invention relates to the field of juicer structure, and particularly to a juicer cup and base storage structure. Background Technology
[0002] Portable juicers have become widely used due to their convenience. Currently, there are two main types of portable juicers on the market: the first type is an integrated structure where the base and the cup are fixed. While this structure ensures that the components are integrated and not easily lost, its overall size is relatively large, making it inconvenient to store and carry. The second type is a detachable structure where the cup and the base can be separated. This type allows the base to be stored inside the cup, thereby reducing the overall size of the machine and making it easier to carry.
[0003] However, existing split-type storage solutions still have significant drawbacks. Some products simply place the base inside the cup without designing a compatible structure between the two. This results in the base lacking effective fixation within the cup, making it prone to shaking, rotation, or even impacts during carrying and transportation. This not only generates noise but also risks damaging the cup or base, leading to a poor user experience. Other products improve stability by adding complex snap-fit and threaded mechanical fixing mechanisms, but this requires significant modifications to the structure of both the cup and the base, increasing the complexity of parts and production costs, while also making the process of assembling and disassembling the base cumbersome for users.
[0004] Furthermore, existing designs often fail to adequately consider storage space utilization. Sometimes, in pursuit of a large-capacity battery, the base height is increased, which may prevent it from being properly stored inside the cup, or prevent the top of the cup from closing properly after storage, thus negating the purpose of portability.
[0005] Therefore, there is an urgent need for a juicer cup and base storage structure that can achieve stable and reliable storage, make full use of the internal space of the cup, and take into account ease of operation and low cost. Summary of the Invention
[0006] The purpose of this invention is to provide a storage structure for the juicer cup and base to solve the above-mentioned problems.
[0007] According to one aspect of the present invention, a juicer cup and base storage structure is provided, comprising a cup and a base.
[0008] The cup body has at least one tapered mating surface, and the equivalent taper angle θ of its generatrix relative to the axis of the cup body satisfies: 0°≤θ≤5°;
[0009] The maximum projected size D1 of the bottom of the cup and the minimum projected size D2 of the top of the cup satisfy: D1≤D2;
[0010] The top of the base is provided with a receiving interface that matches the conical mating surface of the cup body, and the equivalent taper angle ψ of the receiving interface satisfies: 0°≤(θ-ψ)≤0.1°;
[0011] The projected dimension D3 of the bottom support surface of the base satisfies: D1≤D3 <D2;
[0012] The height HE of the base and the height HC of the cup body satisfy the condition: 1.5HE≥HC.
[0013] In some embodiments, the equivalent taper angle θ of the cup body satisfies: 0°≤θ≤1°.
[0014] In some embodiments, the receiving interface surface of the base is provided with an annular groove; the inner wall of the cup is provided with a platform protruding into the cup; when the base is inverted and stored in the cup, the annular groove contacts and supports the platform.
[0015] In some embodiments, an integral elastic sealing ring is provided within the annular groove; the cross-section of the elastic sealing ring is a curved rectangle, and its radius of curvature R and radial thickness HS satisfy: R = (1.5~2.5)*HS; when the base is housed within the cup body, the elastic sealing ring and the conical mating surface of the cup body are interference-fitted, generating radial friction to lock the base; locking is achieved by pressing along the axial direction of the base; unlocking is achieved by rotating the base while simultaneously applying an axial lifting force. The rotation and lifting actions cause the elastic sealing ring to slide upward along the conical mating surface of the cup body, reducing the radial compression and lowering the friction.
[0016] In some embodiments, a permanent magnet array is embedded in the annular groove; a magnetically reinforcing ring is provided on the inner wall of the cup at a position corresponding to the permanent magnet array; when the base is housed in the cup, the permanent magnet array and the magnetically reinforcing ring generate a magnetic attraction force to lock the base.
[0017] In some embodiments, the permanent magnet array adopts a Helbeck arrangement, and the magnetization directions of adjacent permanent magnets in the permanent magnet array differ by 90°.
[0018] In some embodiments, the thickness t of the magnetic reinforcing ring satisfies the following formula: t≥(Bm*Am) / (Bs*π*D4);
[0019] in,
[0020] Bm is the magnetic flux density at the operating point of the permanent magnet.
[0021] Am is the total cross-sectional area of the permanent magnet array.
[0022] Bs is the saturation magnetic flux density of the magnetically reinforcing ring material.
[0023] D4 refers to the median diameter of the annular groove.
[0024] In some embodiments, the inner wall of the cup is provided with strip-shaped baffles; the minimum distance d between the baffles and the outer wall of the base in the stored state satisfies: 0mm≤d≤0.3mm.
[0025] In some embodiments, the baffle strips are arranged in a spiral shape on the inner wall of the cup, and the spiral angle α satisfies: 15°≤α≤60°.
[0026] In some embodiments, the cross-section of the cup body is circular or polygonal, and when the cross-section of the cup body is polygonal, its number of edges n satisfies 4≤n≤12; the cross-sectional shape of the corresponding machine base bearing interface matches the cup body.
[0027] Compared with the prior art, the juicer cup and base storage structure provided by the present invention has the following significant advantages:
[0028] 1. High storage stability and excellent anti-shake and anti-collision effect: By designing the mating surfaces of the cup body and the base as precision conical surfaces with extremely small taper differences, and by setting a platform inside the cup body to contact the groove of the base for support, the base can achieve a large-area tight fit with the inner wall of the cup when stored upside down, effectively limiting the radial movement and shaking of the base. Furthermore, by setting a baffle strip and maintaining a minimal gap with the outer wall of the base, additional radial restraint is provided for the base without hindering the baffle function, achieving double anti-collision protection.
[0029] 2. Optimized space utilization and more compact overall size: By limiting key dimensional relationships, it is ensured that the projected size of both cylindrical and conical bases can be smoothly accommodated by the cup body. Even if the height of the base increases due to accommodating a large battery, its 1.5 times height will always be less than the height of the cup body. Mathematically, this ensures that the base can always be completely stored inside the cup body, greatly improving space utilization and minimizing the overall size of the juicer when stored.
[0030] 3. Simple and intuitive locking and unlocking operation, excellent user experience: This invention provides two excellent locking schemes, both of which are extremely easy to operate. For the friction lock scheme, the user only needs to press the base axially to achieve a firm fixation using the interference friction of the sealing ring; during unlocking, a combination of "rotation + slight lifting" utilizes the conical effect to quickly reduce friction and easily remove the device. The entire process requires no complex alignment or forceful operation, providing a smooth experience. For the magnetic lock scheme, the powerful magnetic attraction of the Halbach array enables a "foolproof" operation where the device automatically attaches and locks upon insertion; during removal, the magnetic force decreases sharply with distance, and the user only needs normal lifting force to overcome the magnetic force and unlock the device, making the operation intuitive and effortless.
[0031] 4. High reliability with redundant backup mechanism: In the magnetic lock scheme, even in extreme situations (such as high temperature causing the magnetic part to fail), the friction force generated by the conical surface can still independently provide sufficient holding force to prevent the base from falling off, forming a reliable mechanical redundancy backup, which greatly improves the safety and reliability of the product.
[0032] 5. High integration of functions and ingenious structure: The baffle strips originally used to improve the stirring effect inside the cup are cleverly combined into anti-collision limiting structures for storage, realizing "multi-purpose use" and avoiding the increased cost and space occupation caused by adding an extra dedicated limiting structure, reflecting the integrity and ingenuity of the design.
[0033] In summary, through a series of innovative structural designs and precise parameter matching, this invention successfully solves the problems of storage stability, space utilization, and ease of operation of existing portable juicers, providing a stable, compact, easy-to-use, and reliable high-quality solution.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] This application provides a juicer cup body and base storage structure, including a cup body 1 and a base 2.
[0038] The cup body 1 has at least one tapered mating surface, and the equivalent taper angle θ of its generatrix relative to the axis of the cup body 1 satisfies: 0°≤θ≤5°;
[0039] The maximum projected size D1 at the bottom of the cup body 1 and the minimum projected size D2 at the top of the cup body 1 satisfy: D1≤D2;

[0041] The projected dimension D3 of the bottom support surface of the base 2 satisfies: D1≤D3 <D2;
[0042] The height HE of the base 2 and the height HC of the cup body 1 satisfy the condition: 1.5HE≥HC.
[0043] In some embodiments, the equivalent taper angle θ of the cup body 1 satisfies: 0°≤θ≤1°.
[0044] In some embodiments, the receiving interface surface of the base 2 is provided with an annular groove; the inner wall of the cup body 1 is provided with a platform protruding into the cup body 1; when the base 2 is inverted and stored in the cup body 1, the annular groove contacts and supports the platform.
[0045] In some embodiments, an integral elastic sealing ring 3 is provided in the annular groove; the cross-section of the elastic sealing ring 3 is a curved rectangle, and its radius of curvature R and radial thickness HS of the elastic sealing ring 3 satisfy: R = (1.5~2.5)*HS; when the base 2 is housed in the cup body 1, the elastic sealing ring 3 and the conical mating surface of the cup body 1 are interference-fitted, generating radial friction to lock the base 2; locking is achieved by pressing along the axial direction of the base 2; unlocking is achieved by rotating the base 2 and simultaneously applying an axial lifting force. The rotation and lifting action cause the elastic sealing ring 3 to slide upward along the conical mating surface of the cup body 1, reducing the radial compression and lowering the friction.
[0046] In some embodiments, a permanent magnet array 4 is embedded in the annular groove; a magnetically conductive reinforcing ring 5 is provided on the inner wall of the cup body 1 at a position corresponding to the permanent magnet array 4; when the base 2 is housed in the cup body 1, the permanent magnet array 4 and the magnetically conductive reinforcing ring 5 generate a magnetic attraction force to lock the base 2.
[0047] In some embodiments, the permanent magnet array 4 adopts a Heilbeck arrangement, and the magnetization directions of adjacent permanent magnets in the permanent magnet array 4 differ by 90°.
[0048] In some embodiments, the thickness t of the magnetically reinforcing ring 5 satisfies the following formula: t≥(Bm*Am) / (Bs*π*D4);
[0049] in,
[0050] Bm is the magnetic flux density at the operating point of the permanent magnet.
[0051] Am is the total cross-sectional area of the permanent magnet array 4.
[0052] Bs is the saturation magnetic flux density of the material of the magnetically reinforcing ring 5.
[0053] D4 refers to the median diameter of the annular groove.
[0054] In some embodiments, strip-shaped flow spoilers are provided on the inner wall of the cup body 1; the minimum distance d between the flow spoilers and the outer wall of the base 2 in the stored state satisfies: 0 mm ≤ d ≤ 0.3 mm.
[0055] In some embodiments, the flow spoilers are spirally arranged on the inner wall of the cup body 1, and the helix angle α thereof satisfies: 15° ≤ α ≤ 60°.
[0056] In some embodiments, the cross-section of the cup body 1 is circular or polygonal. When the cross-section of the cup body 1 is polygonal, the number of edges n thereof satisfies 4 ≤ n ≤ 12; the cross-sectional shape of the receiving interface of the corresponding base 2 matches that of the cup body 1.
[0057] To achieve stable and compact storage, this juice machine has a precise design and matching in the structures of the cup body 1 and the base 2.
[0058] First, regarding the design of the cup body 1:
[0059] The cup body 1 adopts a conical design and has at least one conical mating surface. The equivalent taper angle θ of the generatrix of this mating surface relative to the axis of the cup body 1 satisfies: 0° ≤ θ ≤ 5°. When θ = 0°, the cup body 1 is cylindrical; when θ > 0°, the cup body 1 is in the shape of an inverted cone with a larger top and a smaller bottom. This positive taper design facilitates the pouring of food paste and is not prone to wall hanging. At the same time, in practical applications, the taper angle θ is preferably about 0.3° to balance the pouring convenience and structural strength. In addition, the maximum projection size D1 of the bottom of the cup body 1 is always less than or equal to the minimum projection size D2 of its top (i.e., D1 ≤ D2).
[0060] Second, regarding the design of the base 2 and its matching relationship with the cup body 1:
[0061] The base 2 has a receiving interface at the top that matches the conical mating surface of the cup body 1. The equivalent taper angle ψ of this receiving interface and the taper angle θ of the cup body 1 need to satisfy a strict matching relationship: 0° ≤ (θ - ψ) ≤ 0.1°. This small taper angle difference ensures that after the base 2 is inverted, its outer contour can be highly consistent with the shape of the inner wall of the cup body 1, achieving large-area contact.
[0062] The projection size D3 of the bottom support surface of the base 2 needs to satisfy: D1 ≤ D3 < D2. This size relationship ensures that regardless of whether the base 2 itself is cylindrical or conical, its bottom can be accommodated by the bottom of the cup body 1, and the top will not exceed the opening range of the top of the cup body 1.
[0063] The height HE of the base 2 and the height HC of the cup 1 satisfy the condition: 1.5HE≥HC. This design fully considers the need to increase the height of the base 2 in practical applications to install large-capacity battery cells. Even if the height of the base 2 exceeds the height of the cup 1, this mathematical relationship ensures that the base 2 can be completely accommodated within the internal space of the cup 1, achieving extremely high space utilization.
[0064] Furthermore, regarding the support and anti-sway structure during storage:
[0065] When the base 2 is inverted and stored inside the cup body 1, the annular groove on its surface will be placed on the platform surface that protrudes inward from the inner wall of the cup body 1. This platform will bear the main weight and provide axial support. The platform can be set on the top surface of the baffle ribs or set separately, but it must protrude from the surface of the baffle ribs.
[0066] The strip-shaped baffles on the inner wall of the cup body 1 not only turbulent the flow during stirring, but also form an anti-sway structure with the outer wall of the base 2 when stored. The minimum distance d between the two is generally set to 0.3mm. This extremely small gap effectively limits the radial swaying of the base 2 within the cup body 1, avoiding impacts that could cause noise or damage.
[0067] Finally, regarding safety regulations and ergonomics:
[0068] This design fully complies with safety regulations. The diameter of the top of the cup body 1 is less than 125mm, and the distance from the highest point of the blade's rotation trajectory inside the cup body 1 to the surface of the cup rim is greater than 125mm, ensuring safe use. At the same time, the tapered design, which is wider at the top and narrower at the bottom, is also ergonomic, making it easier to pour food pastes, liquids, or powders without them sticking to the sides or spilling.
[0069] Example 1:
[0070] An integral elastic sealing ring 3 is provided in the annular groove on the surface of the base 2 receiving interface. The elastic sealing ring 3 adopts a special curved rectangular cross-section design, and its radius of curvature R and radial thickness HS of the elastic sealing ring 3 satisfy the optimal proportional relationship: R = (1.5~2.5)*HS. This proportional range is carefully designed to ensure that the elastic sealing ring 3 produces a sufficiently large radial recoil deformation when subjected to shear force, while maintaining good structural stability and not easily undergoing permanent deformation.
[0071] Locking principle:
[0072] In the initial state, the outer diameter of the elastic sealing ring 3 is slightly larger than the inner diameter of the corresponding position of the conical mating surface of the cup body 1, i.e., there is an initial interference δ. When the user presses the base 2 axially into the cup body 1, the elastic sealing ring 3 contacts the conical inner wall of the cup body 1 and is radially compressed, thereby generating a huge static friction force. This friction force is sufficient to overcome the weight of the base 2 itself, so that the base 2 is firmly fixed in the cup body 1, and even if the cup body 1 is inverted, the base 2 will not fall off in a short time.
[0073] Unlocking principle:
[0074] The unlocking process is a complex action that cleverly utilizes the characteristics of a conical surface. When it is necessary to remove the base 2, the user first rotates the base 2 at an angle while applying a slight axial lifting force.
[0075] Rotation: Since the elastic sealing ring 3 is fixed on the base 2, and the inner wall of the cup body 1 is a conical surface, the rotation will change the contact point between the elastic sealing ring 3 and the cup wall. Under the guiding action of the conical surface, the base 2 will have a slight upward axial displacement tendency.
[0076] Lifting: The slight lifting force applied by the user, in conjunction with the aforementioned trend, causes the elastic sealing ring 3 to slide upward along the conical inner wall of the cup body 1. Due to the "larger at the top and smaller at the bottom" characteristic of the conical surface, the upward sliding means that the inner diameter of the cup body 1 where the elastic sealing ring 3 is located gradually increases, thereby reducing its radial compression and rapidly releasing the initial interference δ.
[0077] As the interference fit decreases, the clamping force of the elastic sealing ring 3 on the cup wall and the resulting frictional force decrease sharply. At this point, the base 2 can be easily removed with only a small amount of force.
[0078] In summary, the fixing method of this solution is: pressing the base 2 along the axial direction. The unlocking method is: rotating the base 2 at a certain angle while gently pulling it up simultaneously. This "press to lock, rotate to unlock" operation method is very intuitive, simple and quick, greatly improving the user experience, while achieving a very reliable locking effect.
[0079] Example 2:
[0080] A magnet array (such as a Halbach array) is placed within the annular groove of the base 2, and a magnetic insert (permalloy ring) is embedded in the inner wall of the cup body 1. When the base 2 is retracted into the cup body 1, a magnetic attraction force is generated between the magnets and the magnetic insert, fixing the base 2 in place. Upon removal, the magnetic attraction force decreases sharply with increasing distance by lifting the base 2, thus allowing for easy removal.
[0081] Magnetic block 1: Magnetization direction ↑;
[0082] Magnetic block 2: Magnetization direction →;
[0083] Magnetic block 3: Magnetization direction ↓;
[0084] Magnetic block 4: Magnetization direction ←;
[0085] A non-contact pre-tightening force is established between the base 2 and the cup body 1 by using the Halbach permanent magnet array 4, which replaces the traditional mechanical lock and realizes automatic centering and anti-loosening during storage;
[0086] When the saturation magnetic flux density of the magnetic reinforcing ring 5 material is greater than 0.8T
[0087] Minimum thickness of magnetic ring:
[0088] From the law of conservation of magnetic flux, we can obtain: Φ m =B m ·A m =B S ·A s
[0089] Bm = 1.4T (operating point magnetic flux density),
[0090] Am = Cross-sectional area of the magnet
[0091] Bs = saturation magnetic flux density of the magnetic ring
[0092] As = πD4t (cross-sectional area of the magnetic ring, where D4 is the mid-diameter of the groove),
[0093] Therefore, the thickness can be obtained as...
[0094] Example 3:
[0095] Magnetic-cone coupling preload model:
[0096] The total holding force F(total) is the superposition of the magnetic attraction force F(mag) and the conical surface friction force F(fric):
[0097] F total =F mag +F fric ·sinθ·μ eff ;
[0098] θ is the taper angle of the cup body;
[0099] μ(eff) 0.15~0.25 is the equivalent friction coefficient of the conical surface-sealing ring;
[0100] F(mag) is determined by the magnetic field strength B(g) generated by the Heilbeck array at the air gap g;
[0101]
[0102] η(Halbach) is set to 1.4, which is the enhancement factor of the 4-pole array, and A(mag) is the effective area of the magnetic poles;
[0103] When the user applies an axial extraction force F (pull), the following must be satisfied: F pull ≥F total ·e -k(g0+Δg) ;
[0104] in:
[0105] K = 2π / λ, (λ is the array period);
[0106] g0 is taken as 0.5mm for the air gap in the storage state, and Δg is the lifting displacement;
[0107] Assuming the value is:
[0108] B(g0) = 0.7T, A(mag) = 2000 square millimeters, then F(mag) = 62N;
[0109] The normal force F(fric) = 30N on the conical surface is generated by the radial component of the magnetic attraction force;
[0110] F(total) = 85N. Assuming the weight of base 2 is 10N, then 85N is greater than 10N.
[0111] When Δg = 5mm, Fmag decays to <10N;
[0112] In practice, to reduce the force required for lifting, the effective area of the magnetic poles can be reduced; the Halbach period λ can be halved, the residual magnetism of the magnet can be changed to N38, and a magnetic groove can be opened on the magnetic ring. This can greatly reduce the average force required for lifting 5mm, while maintaining the locking force, thus meeting the dual requirements of secure fixation and easy extraction.
[0113] Redundant locking: When the magnetic attraction fails (such as high temperature demagnetization), the conical surface friction force can still be maintained independently with F(Fric)≥20N.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
